??? VSTi ripping and latency question

Hi,
I am using a rather prehistoric PC, but I don't think I should be encountering
the following problems:
I have a tiny project set up in Cubase SX2, running on a 600 mhz Pentium 2
with 512 MB RAM. Cubase ASIO and kX are set up fine and working, with
latency set to 21.33 ms (for recording and playback).
I set up a single MIDI track routed to the Battery VSTi drum sampler, and
did a short take of BD & Snares.
Next I wanted to add some Hi-Hats but everything went wrong: Timing,
audio rips, pops etc.
I reset the Cubse Audio priority to NORMAL (Default is HIGH), and the problem
relaxed a bit, untill adding a bass line track using NI's FM7,
which reintruduced timing bugs, clicks, bad note-on recording etc.

Am I in for a computer swap, or is there anything that can be done with things
I haven't looked into yet, such as buffer sizes or other?

PS: I am purpously NOT using any DSP or hardware synths -
trying to learn the limits of pure VSTi use!

i think your CPU is holding you ack there… especially the old pentium 2s… my old 750 athlon would barely handel what i tried w/ VSTi… even when i bounced the VSTis to audio tracks… upgrade to maybe a a 1ghz machine, Athlon XP or P4
good luck

Hi gilirose, Dj_stick. FM7 eats much CPU, specially for a P2 (although I don't remember any P2 600, but P3) but even for a slower machine I think it would be cliping, cracking or shouting SOS but not losing sync. Have you selected 48 khz as sample rate? Even though the efforts from E. Gavrilov, 44.1 is not a good choice for soundblasters. (and only works for playback) Does happen the same with Asio DirectX Full Duplex? (48khz) Try to increase latency to 42.66. Also try to avoid midi tracks above audio track in cubase sx2 (There is a known timing issue with it) Is it related just to power? I mean if you change FM7 for, say Neon ( ) does it happen the same?

I hope any of this can isolate the problem.

Nando

BTW, changing Audio priority settings only reported me a waste of time in the past instead of solutions that might be somewhere else.

VSTi Latency

how many ASIO channels are you using? to run cubase as fast as it can, disable all the other ASIO channels. regs, gerald
